Description

A kind of city indoor substation transformer chamber ventilation noise reduction system
Technical field
This utility model relates to power engineering ventilation noise reduction technology field, particularly relates to 110kV city indoor substation and makes an uproar Sound control standard class is main transformer room when two grades.
Background technology
City is congregated district of population, and main transformer is all placed on indoor when standing in design by 110kV urban transformation, passes through House sound insulation and shielding control the running noises of main transformer, but because the safe operation of main transformer needs ventilation and heat, main transformer Door-window opening must be offered again in depressor room, causes the noise of indoor to reach outdoor, surrounding resident is produced impact.At urban environment Today that noise control standard is the strictest, use new sound-deadening and noise-reducing measure to reduce transforming plant main transformer room noise and seem the heaviest Want.
Utility model content
The purpose of this utility model is on the operation characteristic for existing unattended operation transformer station and noise control technique Weak point, it is proposed that a kind of city indoor substation transformer chamber ventilation noise reduction system, before simple in construction and power consumption are relatively low Put, effectively reduce transformer chamber's outdoor noise.
To achieve these goals, technical solution adopted in the utility model is:
A kind of city indoor substation transformer chamber ventilation noise reduction system, is included in transformer chamber and is provided with ventilating noise-elimination BAIYE, Being provided with vent in transformer chamber upper end, also include the fan house being arranged on transformer chamber top, fan house is straight by vent Connect and connect with transformer chamber, blower fan is set in fan house, fan house wall is provided with air inlet and able to turn on or off from So wind exhaust outlet, is provided with impedance muffler at the fan outlet of blower fan, and impedance muffler is arranged on fan house Inside, is provided with noise reduction elbow at the air outlet of impedance muffler.
Also include protecting the intelligent wind control of main transformer indoor transformer to control device, measure the temperature of transformer temperature in transformer chamber Degree sensor, intelligence wind control controller is according to the temperature set, and start and stop blower fan carries out temperature control, sets at natural wind exhaust outlet Air-valve, air-valve linkage intelligence wind control is had to control device.
Also including acoustic-optic alarm, acoustic-optic alarm includes speaker and flash lamp, intelligence wind control controller according to The temperature set, start and stop blower fan is carried out temperature control and is reported to the police by acoustic-optic alarm.
During described main transformer temperature >=45 DEG C, intelligence wind control controller controls blower fan and automatically turns on, and linkage air-valve cuts out;Main During temperature < 45 DEG C, blower fan is automatically switched off, and linkage air-valve is opened.
Transformer chamber and fan house indoor wall surface are laid with sound-absorbing material, and sound-absorbing material uses that barbed delthyrium is micro-to be worn Orifice plate and aluminum fiber acoustic board composite plate.
The maintenance wicket for inspection maintenance at ordinary times is had on described ventilating noise reduction soundproof door.
This utility model is compared with traditional transforming plant main transformer chamber ventilated noise reduction technology, and this utility model solves following asking Topic: one is the cross-ventilation ventilating problem under the conditions of normal working temperature in transformer chamber;Two is that unattended operation transformer station is being led Become and how in the case of not having personnel to operate in time, to reduce indoor temperature when room temperature exceedes design temperature, ensure that equipment is normal The problem run;After three are fan starting, how under conditions of positive mechanical is ventilated, permitting noise control outside transformer chamber Problem in the range of Xuing.This utility model, after using available ventilation and noise reduction measure, effectively meets transformer chamber's room ventilation and wants Outdoor noise is significantly reduced while asking.Show through effective monitoring result of environmental monitoring part, outside transformer substation noise < 50dB, meets urban area two noise like and controls the requirement of standard.
Accompanying drawing explanation
Fig. 1 is this utility model transformer chamber and fan house generalized section;
Fig. 2 is this utility model roof ventilator room floor map;
Fig. 3 is this utility model roof ventilator room inner wall surface schematic diagram;
Fig. 4 is this utility model roof ventilator room wall face schematic diagram.
Detailed description of the invention
Below in conjunction with embodiment, this utility model is described further.
Embodiment
As shown in Fig. 1 ~ 4, the 110kV transformer chamber of the present embodiment and the city indoor substation main transformer of radiator chamber not split The ventilation noise reduction system that room uses, including transformer chamber 1 and fan house 7;Ventilating noise-elimination BAIYE it is provided with on the downside of transformer chamber gate 2, indoor are provided with attemperating unit 3;Transformer chamber roof is provided with fan house 7, and fan house 7 inner blower 4 is eliminated the noise with impedance type Device 5 is connected in series;Air inlet 11 and natural wind exhaust outlet 12 are set on fan house 7 interior wall, on natural wind exhaust outlet It is provided with and the air-valve 8 of attemperating unit 3 linkage;Maintenance wicket 9, noise elimination ventilating blind 10 and fan outlet it is provided with on exterior wall 13;Fan outlet termination is provided with bend muffler 6.
This utility model method of operation under conventional sense is that blower fan 4 cuts out, and air-valve 8 is opened, by ventilating noise reduction hundred Leaf 2 natural air inlet, air-valve 8 and ventilating noise reduction BAIYE 10 natural exhaust, generally natural ventilating status.When transformer chamber, temperature exceedes During design temperature, attemperating unit 3 controls blower fan 4 and opens, and the air-valve 8 linked with it cuts out, and is naturally entered by ventilating noise reduction BAIYE 2 Wind, indoor high-temperature gas passes sequentially through blower fan 4, impedance muffler 5 and bend muffler 6, and room air is arranged by positive mechanical Outside wind mode discharge chamber.
Because transformer chamber 1 and fan house 7 indoor wall are all laid with sound-absorbing material, can effectively absorb and propagate to body of wall Indoor noise, main transformer room noise is mainly outwards propagated by shutter and wind passage mouth, is therefore entered these noise transmission approach Row effectively controls, and both can reduce transformer chamber's outdoor noise.During natural ventilating status, at inlet and outlet, it is respectively provided with sound absorbing louver, Effectively suppression noise outwards can be propagated;During positive mechanical ventilation state, linkage air-valve cuts out, and high-speed gas passes through blower fan, warp Impedance muffler and bend muffler discharge, the noise that impedance muffler and bend muffler can effectively spread out of in filter chamber The noise produced with elimination high velocity air, meets the requirement of criterion for noise control.
This utility model patent, after using available ventilation and noise reduction measure, effectively meets transformer chamber's room ventilation requirement Significantly reduce outdoor noise simultaneously.Show through effective monitoring result of environmental monitoring part, outside transformer substation noise < 50dB, Meet urban area two noise like and control the requirement of standard.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.One's own profession Skilled person will appreciate that of industry, this utility model is not restricted to the described embodiments, described in above-described embodiment and description Principle of the present utility model is simply described, on the premise of without departing from this utility model spirit and scope, common in this area The simple change of technical staff and within replacing and being all protection domain of the present utility model.
